    Video shifting

    snagswolf Level 1

      It seems like the video is shifting all over. If I cut it at a certain point, it will playback correctly. But if I play it again, the cut point seems to shift to a different spot. Also, if I block a section and slow it down, next time I play it the part that's slowed down is in a different spot. It's pretty much useless to me like this.

          What version of Premiere Elements on what computer operating system?

           

          What are the properties of the source video (including brand/model/settings of the camera that recorded the video)?

          What project preset is set to match those source media properties?

           

          What are you using as the cutting Tool? What are you using for slow motion - Time Remapping or something else?

          After you have made your edits, do your Timeline render the Timeline content that you just edited?

           

          Please consider and supply more information.

           

          Thank you.

            Using Premiere Elements 14 on Windows 7.

             

            Imported video properties:

            Type: AVIMovie

            File Size: 417.4 MB

            Image Size: 1280 x 720

            Frame Rate: 30.00

            Source Audio Format: 22050 Hz - 16 bit - Mono

            Project Audio Format: 22060 Hz - 32 bit floating point - Mono

            Total Duration: 00:02:22:26

            Pixel Aspect Ratio: 1.0

            The camera is on a Syma 8XC quadcopter, and it's listed as a 2MP HD

             

             

            After reading another thread, I played around with the project settings, and decided this one was the closest match:  HDV 720p 30

            But it's still not working.

             

            Using the little scissors icon on the vertical red line as the cutting tool. For slow motion, I'm selecting the clip segment and then using Clip->Time Stretch.

             

            Tried rendering, but it doesn't seem to help.

             

            Thanks

              We need to know what kind of .avi file this device is recording. AVI is just a file extension (wrapper format) for the video and audio compressions. The video and audio compressions can be different .avi to .avi under the .avi wrapper. And, some do not fare well in Premiere Elements. Please find out what type of .avi you have.

              GSpot readout  GSpot Codec Information Appliance

              or

              MediaInfo readout (Tree View)  http://sourceforge.net/projects/mediainfo/

               

              Worse case is probably Xvid.avi,

               

              MediaInfo can serve two purposes - tell us the video and audio compressions. And, it can tell us whether or not this device is recording with a variable frame rate instead of a constant one. If you find 3 frames rates listed for the file in MediaInfo video readout that = variable frame rate with which Premiere Elements has problems. Typical solution is to obtain the H.264.mp4 with the variable frame rate into HandBrake to obtain the H.264.mp4 with constant frame rate which you take into Premiere Elements project.

              https://handbrake.fr/

               

              Let us rule in or out these basic issues, and then we can get more specific with what is going on in the workspace with Time Stretch and the rest.

               

              Any questions, please do not hesitate to ask.

               

              Thank you.

              Add On....from what I can determine this is a 1280 x 720 @ 30 progressive frames per second from your description...I might suggest a different project preset moving forward. But, for now I want to see the details mentioned above. Is there an orange line over your Timeline video content when you first drag that content to the Timeline?

                Tried the Handbrake thing - loading the file and saving it as an MP4 with a fixed frame rate, and that seemed to fix the problem. I'll do some more checking and come back tomorrow to let you know.

                 

                Thanks.

                  Thanks for the very important troubleshooting information.

                   

                  What you have is MotionJPEG.avi 1280 x 720 @ 30 progressive frames per second video. The audio is PCM mono.

                  Premiere Elements has its problems with MotionJPEG.avi but usually just trying to get it imported.

                   

                  If you do decide you want to go with the HandBrake version H.264.mp4 1280 x 720 @ 30 progressive frames per second, I would suggest the following Premiere Elements 14 project setting (set manually to make sure that we have the project preset that we want to confirm the workflow details).

                  NTSC

                  FLIP

                  Flip Mino HD and Ultra HD 30p

                  To set the project preset manually use the following scheme

                  • Open the project to the Expert workspace, and go to File Menu/New Project and Change Settings.
                  • In Change Settings, set the project preset as indicated above. OK out of there.
                  • In the New Project dialog that opens, rename the project and make sure to have a check mark next to "Force Selected Project Setting on This Project". OK out of there.
                  • Back in the Expert workspace, import your source media using Add Media/ choice.

                   

                  If we have the correct project preset, then the file should arrive on the Expert workspace Timeline with no colored line over its content.

                   

                  We will be watching for your results. I am not sure of my schedule tomorrow. I will get back to your thread as soon as I can tomorrow.

                   

                  Thanks for the follow up.
